She's already got a son with rapper Tyga and a daughter with ex-fiancé Rob Kardashian.

And now rumour has it that Blac Chyna is expecting a third child with her 18-year-old boyfriend, rapper YBN Almighty Jay.

According to MTO News, the former stripper is two and a half months pregnant, and was spotted rubbing her 'bump' as she walked through Los Angeles Airport on April 27.

Indeed, he previously revealed they're not using contraception and she certainly didn't seem shy about flaunting her curves - or sucking Jay's face off - when they greeted fans at a Lashed Ladies luncheon on April 29.

Mirror Online has contacted reps for Blac - who is mother to son King, five, and one-year-old daughter Dream - for comment.

Chyna met her latest lover on dating site Christian Mingle, and he admitted they've not been bothering with condoms.

"How did I meet Blac Chyna? I was searching on Christian Mingle and s*** and I seen her profile pop up and I'm like, 'This b**** fire,'" he told Jumper.

"So I slid in her Christian Mingle messages and s*** and she responded to my email so then we had linked up and s***... I don't wear a condom!
